The cradle consisted of a wooden box that was on rockers, a metal strainer on top and two slanting shelves with rationalize slats of wood to trap grains of gold with the box. Two men were i ndispensable to work the machine. One man shoveled sand and lecture onto the sieve, plot a second man, rocked the cradle backwards and out front with on hand and use a long-handled butterball to pelt in water system. Sometimes, they worked in a team of four, because practically the shelves became cover with mud, and was preventing the gold from being caught. Later on, cradles were replaced by pour boxes or presbyopic Toms. A number of boxes were placed pole to end to get to a long channel. When the running water carried the dirt through the boxes, the gold was caught in the slats nailed to the bottom of the boxes. Puddling was used when the clay deposits were heavy.
